Excuse my stupidity but this is piling for the tower?

Hi CDJ, I've been told that this development will feature multiple tower cranes, is this still the case or will their revert to crawlers?

Cheers!

It's the piling which will form the retaining wall for the new basement under the tower. There is a huge 5-level carpark to be constructed first before the tower will move up above plaza level.

Definitely 1-2 tower cranes for Festival Tower. Possibly an extra tower crane for the carpark slabs and columns.

Getting on with the job! Very nice to see.

$30m contract for huge Festival plaza carpark

Adelaide’s Festival Square carpark project zooms ahead as $30m contract awarded to Delta Group

One of the largest earthworks contracts in South Australia’s construction history has been awarded as a key Riverbank project continues to gather pace.

Walker Corporation has handed a $30 million contract to national civil contractor Delta Group for its $500 million development at Festival plaza, which will deliver arts upgrades, a new carpark and office tower as part of the project now known as Festival Square.

A new 1600-space, five-level underground carpark will be the focus of the contract — which has resulted in Delta opening an office and yard in Adelaide off the back of being awarded it.

As part of the contract, Delta will move an estimated 130,000m3 of material from the site in a 14-month program, drilling 15m into the ground.

Walker Corporation South Australia Senior Development Manager Ben Moore said this would get the site ready for the construction of the carpark this year.

“We only started work in May of last year when we were formally provided access to the site, so it’s been a very busy work schedule since then,” he said.

“The demolition and excavation process is literally huge, it’s creating an enormous space that is starting to give a sense of the scale of the development.

“In some ways, it’s a pity that the hoardings prevent people from seeing what’s happening. I think they’d be quite impressed.”

The development will create 10,000m2 of public space modelled on international city squares such as Plaça Catalunya in Barcelona and Leicester Square in London.

It also includes a 23-storey office tower between the Casino and Parliament House, providing 40,000m2 of premium office space, and a large-scale retail and commercial precinct featuring cafes, restaurants and retail outlets.

Mr Moore said the development was the missing piece of the puzzle that will make the Riverbank “a true destination for locals and tourists alike”.

Also taking place in the precinct is the $330 million expansion by the Adelaide Casino, which includes a 123-room luxury hotel, three bars and three signature restaurants.

I wonder how deep the water table in the area is, and if it rises when the Torrens floods. What happens if the bottom of the car park is below it?

I wonder how deep the water table in the area is, and if it rises when the Torrens floods. What happens if the bottom of the car park is below it?

What are the chances of a flooding event that will result in several meters (at least) of water levels rising around the torrens for flood waters to actually impact things like the festival center and casino?

The flood would have to be fairly significant for it to even reach as high as King William road let alone make it to the car park location.

[[Shuz]]

The water table would be virtually nonexistent seeing as the Torrens Lake is a man made lake not a natural one. Absolutely zero concern of any flooding events.

[Nort]

Yeah, for the Torrens to flood that high would also involve it flooding over the weir, meaning that water level is all the way to the coast. If Adelaide somehow got that flooded then we've lost the entire coastline already.

The site of the car park does rise a fair bit from the river heading up to North Terrace. Generally basements are constructed either with a waterproofing membrane (or waterproofing admixture within the concrete) to the perimeter walls and/or perimeter spoon drains on each level to collect any runoff which does make it into the basement.

I was involved in a job here in Brisbane a couple of years back where a whole city block basement car park 7 levels deep was constructed adjacent to the Brisbane River. For a basement at this scale, water will seep in from the surrounding soil particularly after it rains.

Thank you for understanding that the question was about ground water not surface water, and giving a helpful reply. I have no idea of the hydrology of the Adelaide Plains, so had no idea if it could be an issue.

The water table in this vicinity is actually above the bottom of the lake. It is why the lake manages to maintain a constant level, even with months of hot dry weather during Adelaide summers. Several years ago the lake was accidentally drained by a weir maintenance worker (or sabotage) and overnight the lake completely drained. Much angst about our premier water feature being a mud bowl and no rain in sight, however within a week, water had risen from the water table almost half filling the lake. Having said that you would assume the engineers have accounted for any water seepage in the design. There was a situation at Henley, where the basement level of a new apartment construction required constant pumping of water from the lower lever as obviously this was overlooked, but hopefully not in this case. As AG has pointed out, the basement level may well be above the surface of the lake anyway.
